Compatible toner kit for Kyocera TASKalfa series

This four-cartridge set replaces Kyocera TK-8307 and Copystar TK-8309 toners. It fits Kyocera TASKalfa 3050ci, 3051ci, 3550ci and 3551ci colour laser printers plus the matching Copystar CS models. The pack contains one black, one cyan, one magenta and one yellow cartridge for full-colour printing. Buyers who need individual cartridges or a different yield should look elsewhere.

Printer model verification before purchase

Confirm that your device is one of the listed Kyocera TASKalfa or Copystar models before ordering. The cartridges are designed for the 3050, 3051, 3550 and 3551 series only. Using them in other Kyocera or Copystar machines may cause fitment or recognition issues. No firmware version or regional variant data is supplied, so check your printer’s exact model number on the label.

Yield rated to ISO/IEC 19798 at five percent

The black cartridge is rated for 25000 pages and each colour cartridge for 15000 pages under the ISO/IEC 19798 test method at five percent page coverage. Actual page counts will vary with graphics density, page format and environmental conditions. Continuous high-volume jobs will typically achieve results closer to the rated figures than intermittent short runs.

Questions about this item

What cartridges are included in the 4-pack and do I need to buy any colour separately?

The pack contains one black, one cyan, one magenta and one yellow cartridge; all four colours are supplied so nothing extra is required.

How do I decide between the Kyocera TK-8307 and Copystar TK-8309 versions for my printer?

Both part numbers refer to the same compatible set; choose the one that matches the label on your current cartridges — TK-8307 for Kyocera TASKalfa 3050ci, 3051ci, 3550ci, 3551ci or TK-8309 for Copystar CS3050ci, CS3051ci, CS3550ci, CS3551ci.

What does the 25,000-page black yield mean for everyday printing on my TASKalfa 3551ci?

It is measured under the ISO/IEC 19798 standard at 5 % coverage, so typical office documents will approach that figure while heavy graphics or photos will reduce the actual page count.
